TO ALL WHOM IT MAY CONCERN: I

Be it known that I, THOMAS HALL, of Boston, in the county of Sufl'olk, and State of: Massachusetts, have invented an Improvement in Voltaic Armor Bands and Bracelets; and I dohereby declare that the followihg' is afull and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

Figure-I, plan showing the metallic plates.

Figure II, plan of the back of the band.

Figure III, sectionthrough the middle of the plates.

Figure IV, position of plates when bent backward.

Figure V, position of the plates when applied to a limb.

My improvement relates to -the mode of constructing and using alternate plates of difl'ereut metals for the purpose of relieving pain or curing a. certain class of nervous or other diseases, and consists mainly in the application to the limbs, and other parts of the body, of bands, bracelets, fillet s, or girdles, which surround the part afl'ected, being placed as near to the seat of the pain as possible. The plates are slightly decomposed by the moisture of the skin, and voltaic action takes place, thus inducing warmth, and. applying to practical use the sedative and other influences due to electric currents. I i

Letters Patent of the United States were issued to Inc on the seventh day of February, 1865, for improvement in Voltaic Shoe Soles." This present improvement diii'rsfrom my former invention mainly in the mode of attaching the plates to each other and to the backpiece, and in the use of a suitable buckle or clasp for the purpose of fastening the band or bracelet to the arm or other-parts of the-body.- Instead ofeyelets for fastening-the series of plates G H, G H, 860., I- connect. them to each other, as at I I,two curved lips upon each plate entering into corresponding slots or holes in the contiguous plate. The series of plates have a leather or other suitablc'backing, A A, provided at one end with a strap nndJJuekle, C D, and at the other end with a tongue, 13. The curved lips I I, which serve to connect the plates to each other, are also used as rivets or-i'astnings for holding the plates to the back piece. 'Incisio'nsare made through the leather 'or cloth, and

the curved lips are thrust through, and-then clinched or fiattcned down upon the back piece. Wheuthe build 101 bracelet is placed upon the arm or other part of the body the strap B and buckle Dhold it in the position shown in the Fig. V, and the series of metallic plates G H being in contact with the skin 8. currentof electricity is generated,and continues to exert its influence so long as the band remains upon the arm. The motion of the muscles and the occasional flexure of the band keep the 'points of contact bright, thus insuring perfect electrical connection.

What I claim, and desire to secure by Letters Patent, is' The series of plates of difl'erent metals attached to each other by double hooks formed upon one side of each plate, and entering corresponding slots cut at the opposite edge of each plate, the hooks being passed through the leather or cloth strap and clinched upon the side opposite to the plates, substantially as hereir described.
